head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Pure Mechanics
A classic side-scrolling platformer following Aladdin through Agrabah and beyond.

Execution · Pure Mechanics
Gleefully gory physics platformer about surviving user-made obstacle courses.
Aladdin leans Execution (Pure Mechanics); Happy Wheels leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Aladdin
Precise platforming jumps and sword-timing are demanding.
Happy Wheels
Twitchy ragdoll vehicle control through traps
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Aladdin
No adaptive opponent, fixed enemy patterns.
Happy Wheels
Levels are static obstacle courses
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Aladdin
Some randomness in enemy placement and drops.
Happy Wheels
Physics wobble adds run-to-run chaos
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Aladdin
Level routes are learnable but execution dominates.
Happy Wheels
Trap memorisation and route choice
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
